Studies on transport and thermodynamic properties of binary mixtures of octan-1-ol with chloroform, 1,2-dichloroethane and 1,1,2,2-tetrachloroethane at 298.15 and 308.15Â K

Viscosities (η) of binary mixtures of octan-1-ol with chloroform, 1,2-dichloroethane (DCE) and 1,1,2,2-tetrachoroethane(TCE) have been determined at 298.15 and 308.15 K and atmospheric pressure for the whole composition range. Deviations in viscosity (Δη) from the mole fraction average have been derived from the experimental data. Excess functions of free energy of activation (ΔG⁎E), rheochor (rhE) and Dunstan's parameter (CDE) have also been computed from the experimental viscosity data. These quantities have been fitted to the Redlich-Kister polynomial equation and the results analyzed in terms of molecular interactions and structural effects. The viscosity data have been correlated using Kendall-Monroe, Grunberg-Nissan, Tamura-Kurata, Hind-Mclaughlin Ubbelohde, Katti-Chaudhary viscosity models and McAllister's three body interaction model at different temperatures.
